After Sharpie editing my BC core I decided I both wanted to actually read the Marines' abilities, not use up all of my ink (and be left with a wet mess of a character sheet), AND add corrections...

Maybe someday I'll get paid to edit too, jk, FFG doesn't edit unless its a bored game or the tome's a year old.
P.S. I've considered ink saving the hit location figure; let me know if any fixes needed.
